IMO, your above referenced amount in a single visit would not be considered at all high by any metric anywhere in the world of H boutiques TODAY. Some of us spend this amount in a normal visit, assuming we find items we love. A specific 1.5X visit for me was only two RTW pieces, namely, a toile and leather jacket and leather skirt. My local store is Madison, and I’ve only just started with a Liat SA. I do also shop with my FSH SA a couple of times a year, but FSH is the only location where I’ve gotten two kelly bags in two visits with little to no prespend.
If you do manage to get something like a JPG Kelly pouchette at 1.5X, many of us would be very interested in hearing about it. During Covid, it was my understanding that special offers did happen, but those days are long over.
ETA: I seem to recall my NY SA said the Kelly cut has been out of production, and the JPG kelly pouchette makes sporadic appearances. It was also my understanding in the US that if you buy more than one all leather couch (each about 170K USD), some kind of offer might pop up. A sizable number of H clients furnish their homes in Hermes, so this isn’t as unusual as it might seem.
